Inkjet Printed Metamaterial Loaded Antenna for WLAN/WiMAX Applications

In this paper, the design and performance analysis of an Inkjet-printed metamaterial loaded monopole antenna is presented for wireless local area network (WLAN) worldwide interoperability microwave access (WiMAX) applications. The proposed structure consists two layers, one rectangular tuning fork-shaped antenna, another layer inkjet-printed superstate. designed using four split-ring resonators (SRR) with H-shaped inner to achieve negative-index properties. fabricated on low-cost photo paper substrate material a conductive ink-based inkjet printing technique, which achieved dual negative refractive index bands 2.25–4.25 GHz 4.3–4.6 GHz. fork operate at WLAN WiMAX bands. printed 30 × 39 1.27 mm3 Rogers RO3010 substrate, shows wide impedance bandwidth 0.75 (2.2 2.95 GHz) 2 dB realized gain 2.4 After integrating structure, becomes 1.25 (2.33 3.58 2.6 have been increased developed quad SRR based metasurface by 500 MHz 0.6 dBi respectively. Moreover, can be used 2.5 contribution work develop cost-effective inject enhance WLAN/WiMAX antenna.
